what i normaly do when somebody is in goalline formation is i run 46 engage 8
i hot route my 2 corners to flat zones, one blitzing LB on the strong side to a purple zone, and user the middle. the goalline formation has almost ZERO deep passes. normaly one TE will do a corner, the other will do some kind of crossing route and the 3rd will block and the FB will go to the flats. good at stopping the run and good coverage for the pass if you can user
